Significance Two of the most debilitating and scientifically challenging diseases of the 21st century are cancer and neurodegeneration. Although cancer results from excessive cell growth, neurodegeneration is a consequence of excessive cell loss. Dysfunction of the same key regulators, including oncogenes and tumor suppressors, may cause both diseases. We report that LPS and IFN induce apoptosis-stimulating protein of p53 with signature sequences of ankyrin repeat-, SH3 domain-, and proline-rich region-containing protein 2 (ASPP2) transcription through a signal transducer and activator of transcription 1 (STAT1) -dependent but NF-κB RELA/p65-independent pathway and that ASPP2 mediates LPS-induced apoptosis. Thus, the identified STAT1/ASPP2 pathway reveals an important function of ASPP2 in the cellular response to inflammation and infection and connects neuroinflammation to cell polarity and tumor suppression.
